INFORMATION TO BE INCLUDED IN THE REPORT Item 1.01 Entry into a Material Definitive Agreement. The information required by this Item 1.01 is incorporated
herein by reference to Item 2.03 of this Current Report. Item 2.03 Creation of a Direct Financial Obligation or an Obligation Under an Off-Balance Sheet Arrangement of a
Registrant. On July 11, 2011, Waste Connections, Inc. and certain of its subsidiaries, as borrowers,
entered into a new Amended and Restated Credit Agreement with Bank of America, N.A. and the other banks and lending
institutions party thereto, as lenders, Bank of America, N.A., as administrative agent, and J.P. Morgan Chase Bank,
N.A. and Wells Fargo Bank, National Association, as co-syndication agents. Our new credit agreement is comprised of a $1.2 billion revolving credit facility which matures on July 11, 2016.  We
have the ability under the new credit agreement to increase commitments from $1.2
billion to $1.5 billion, subject to conditions including that no default, as defined in the new credit agreement, has
occurred, although no existing lender has any obligation to increase its commitment. We used proceeds from the new
credit agreement in order to refinance our previous $845 million credit agreement, which had a maturity of September
27, 2012.  As a result of the refinancing of our previous credit facility, we currently have
approximately $587.3 million of outstanding obligations under our new credit agreement, including letters of credit. Under the new credit agreement, there is no maximum amount of standby letters of credit that can be issued; however,
the issuance of standby letters of credit reduces the amount of total borrowings available. The new credit agreement
requires us to pay a commitment fee ranging from 0.200% per annum to 0.350% per annum of the unused portion of the
facility. The borrowings under the new credit agreement bear interest, at our option, at either the base rate plus the
applicable base rate margin on base rate loans, or the LIBOR rate plus the applicable LIBOR margin on LIBOR loans. The
base rate for any day is a fluctuating rate per annum equal to the highest of: (1) the federal funds rate plus one half
of one percent (0.500%); (2) the LIBOR rate plus one percent (1.000%), and (3) the rate of interest in effect for such
day as publicly announced from time to time by Bank of America as its prime rate. The LIBOR rate is determined by the
administrative agent pursuant to a formula in the new credit agreement. The applicable margins under the new credit
agreement vary depending on our leverage ratio, as defined in the credit agreement, and range from 1.150% per annum to
2.000% per annum for LIBOR loans and 0.150% per annum to 1.000% per annum for base rate loans. The interest rate applicable under the new credit agreement is
currently the LIBOR rate plus 1.400% per annum, a 0.775% per annum increase in the corresponding interest rate under
our previous credit agreement. The borrowings under
the new credit agreement are not collateralized. The new credit agreement contains representations and warranties and places certain business, financial and operating
restrictions on us relating to, among other things, indebtedness, liens and other encumbrances, investments, mergers
and acquisitions, asset sales, sale and leaseback transactions, and dividends, distributions and redemptions of capital
stock. The new credit agreement requires that we maintain specified financial ratios. We expect to use the new credit
agreement for acquisitions, capital expenditures, working capital, standby letters of credit and general corporate
purposes.  2

Several of the banks that are parties to our new credit agreement, including their predecessors and affiliates, have in
the past performed, and may in the future from time to time perform, investment banking, financial advisory, lending
and/or commercial banking services for us and our subsidiaries, for which the banks have received, and may in the
future receive, customary compensation and reimbursement of expenses. The above description of our new credit agreement does not purport to be complete and is qualified in its entirety by
reference to the Amended and Restated Credit Agreement, which will be filed as an exhibit to our Quarterly Report on Form 10-Q
for the quarter ending September 30, 2011. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be
signed on its behalf by the undersigned hereunto duly authorized. WASTE CONNECTIONS, INC.
